ATV15C640JB-HF is a TVS - Diodes (transient voltage suppressor diode), or a voltage suppressor. It is a voltage regulator with a low current capacity and a superior thermal design down to 4 uA at 8mA current. It can be used as an interrupter, as well as for transient suppression and other applications.

This device works by regulating the incoming voltage with an on-chip MOSFET. It then uses its internal parameters to adjust the current passing through it. The device is interconnected with a monolithic resistor to reduce the voltage across it, and these resistors are connected in series to the MOSFET to further reduce the voltage.

The ATV15C640JB-HF is mainly used in power supply circuits, as it can provide extra protection when the input voltage spikes. It is ideal for AC and DC power applications as well as automotive applications. Its output voltage is adjustable between 0.8V to 6V and its maximum current capacity is 8mA.

The device comes in two packages; an SMT and DIP version. The SMT version has a maximum dissipation of 500mW and a peak power capability of 2.2W. The DIP version has a maximum dissipation of 1W and a peak power capability of 2.8W. It also has a higher input capacitance of 100nF and lower reverse leakage of 10mA.

Other applications for the ATV15C640JB-HF include:

• Telephone circuits;
• Computer applications;
• Power line communications;
• Over-voltage and reverse polarity protection;
• High-speed data transmission;
• Portable electronics;
• Industrial control and automation;
• Data processing and storage.

The ATV15C640JB-HF is a reliable device due to its superior thermal design, low current capacity, adjustable output voltage, and high peak power capability. This makes it suitable for a wide range of applications where over-voltage protection is needed.
